I used the basic recipe from Low Carb Layla's peaches and cream popsicles and played around with it.
Chocolate Mint Creamsicle
1 1/4 cup heavy whipping cream
1 Tbsp unsweetened cocoa powder
1/2 cup SF chocolate syrup
2 very small drops of peppermint oil(stronger then extract)
Mix ingredients and pour into molds. Freeze 4 hours or overnight. If you can't find peppermint oil, peppermint extract will work too. Add 1/2 tsp then taste. Add more to get your desired flavor.
